Package: slirp
Severity: important
Tags: patch upstream
Dear Maintainer,
When trying to use slirp with user-mode-linux (eth0=slirp) under Debian
bookworm (amd64), I noticed that as soon as I up the virtual interface,
slirp prints its usual banner and immediately exits with status 1. The
slirp process started by UML becomes a zombie and there's no network
connectivity. Some debugging led me to believe that the cause is
signedness difference at src/main.c:955 in the
if (timeout.tv_usec == -1) { ... }
comparison, which makes the condition always false, thus reaching the
select() call with timeout.tv_usec (of unsiged type) set to 0xffffffff
(that is -1 converted to unsigned) and thus hitting EINVAL. Adding an
explicit cast via the below patch helped. This problem might affect
64-bit architectures only; I tested on amd64. Please consider fixing
this one way or another.
Thanks,
Feri.
